Updating R version of JupyterLab

Question

I am using R in Jupyterlab with Anaconda .I need to update my R version of Jupyterlab. The r-base version of Anaconda is 4.1.1, but when I write version to Jupyter cell, it says my R version is 4.0.3. How can i update it 4.1.1 ? Thank you.

Recommendation: Favor Creation Over Mutation

Trying to update release versions of core environment software (e.g., r-base=4.0 to r-base=4.1, python=3.6 to python=3.9) is often a waste compute resources, since it involves changing nearly every package in the environment and makes for a difficult solve for conda. It is usually far more efficacious to create separate environments for each release version you use:

Create R 4.1.1 Kernel Environment

# include additional packages at "..."
conda create -n r_4_1_1 r-base=4.1.1 r-irkernel ...

As long as the environment with Jupyter Lab has nb_conda_kernels installed (see this SO answer), this will automatically make the new R 4.1.1 environment available as a kernel.
